The methanol extract contains considerable phenolic (117.95±3.22 mg GAE/g) and flavonoid (120.14±2.31 µMRE/g) with no much significant correlation between the total content of phenolic and flavonoid and antioxidant potential was found as IC50 value of 271±3.5µg/ml were recorded in ABTS assay and IC50 value of 306± 4.21µg/ml was found in DPPH assay.
